Cos-IQ 23% Vitamin C Face Serum for Glowing Skin 30ml| Advanced Molecular Skincare Technology | Highly Stable, Non Irritating, Non Sticky| Brightening & Hydrating Formula For Men & Women

I’ve tried a lot of Vitamin C serums before, but most either irritate my skin or don’t show any results. COSIQ’s 23% Vitamin C serum was a pleasant surprise! It’s lightweight, absorbs quickly, and doesn’t feel sticky at all. I’ve been using it for about 3 weeks now, and I can already see my skin looking brighter and more even-toned.What I love most is that it doesn’t have that weird citrus smell or cause any tingling. It works well under sunscreen and makeup too. Definitely recommend it if you’re looking for a high-potency Vitamin C serum that’s still gentle on the skin.
